Installation
This custom-fit T-connector plugs into your vehicle's factory tow package wiring harness, which is located behind the rear bumper, along the driver's-side frame rail.
Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plug on your automobile and the 4-pole connector itself - to help prevent corrosion.

This was a quarter of the price that Jeep wanted to sell it to me for and with some personal modifications/additional wiring I now have two versatile means of hooking up my trailer lights!

Excellent product and very straightforward to install. Opted for the Curt T-Connector C55515 and will have my dealer flash computer to recognize new configuration. Already used hitch with trailer to haul several heavy items up to about 2000lbs with no trouble whatsoever. Should have got this years ago!

2014 Jeep Grand Cherokee
Fast shipping, easy install, product as described. The only complaint was the need to take the vehicle (2014 Jeep Grand Cherokee) to dealer for ECU flash. I know this is not Etrailer's fault so not knocking them. I just hope to save other people time in the future if they think they are just able to plug in and tow.

8/02/2016 Update - replaced the 2014 Grand Cherokee with a 2016 Grand Cherokee, forced dealer to swap the hitch and wiring from old jeep to new jeep as part of the deal. Item still working as described, no complaints.
by: JASON GONSALVES08/08/2013
avalanche owners,easy too install i highly suggest when installing pull the cable through the hitch its open at the end less wire being exposed,(this is from my experience) other than that i am very happy with an troop,Patrick B,an everyone at etrailer.com provided great costumer service i will be buying from them soon.

Plug n Play once you turn on the trailer functions in the computer... dealer wanted $175 to enable the lights. It can be done DIY for around $20.

2013 Jeep Grand Cherokee
Item was great and worked like a charm. Only problem was the vehicle. I used it on a 2013 Jeep Grand Cherokee. The vehicle came standard with the 7 pin connecter but since it didn't come with the "towing package", the dealer had to reprogram the system to start sending voltage to the vehicle connector.

What was the cost to have the grand cherokee reprogrammed, and how long did the reprogram take?

Jim the dealer charged $50 and it only took about 10 minutes once they figured out the problem. They spent about 4 hours figure it out tho.

I was not aware at the time i purchased this item that it was not what i needed. The page told me i needed this item to complete my set up so i bought it. little did i know that my vehicle does not have a factory wiring harness so what i bought was useless. I am going to have to return this item. The page should also make it more clear of what you may need before you purchase something and you wait almost 2 weeks for it to arrive. I had to order what i needed else ware to be here when I need it to be.

Thank you for your review. The 2019 Dodge Durango does need a factory towing package to use this wiring harness. Since the 2019 Dodge Durango does not have the factory towing package you will need part Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part C56336.

2014 Jeep Grand Cherokee
Question for you please. The hitch itself has been great, but I can't get the wiring harness for the lights to work on the trailer. I'm reading different things online, sounds like my Grand Cherokee may have to be programmed for the lights to work? Are you familiar with that? Is that the case?
Thanks in advance!
by: John R.05/09/2018
I chose the Draw tight Max Frame Trailer Hitch for its known quality, i like it comes powder coated to reduce unsightly rust and to keep that fresh look.
I chose the this hitch for my all around light and heavy duty needs.
The Draw Tight Ball Mount is a quality enhancement to this hitch.
I chose the 2" chrome ball for its quality and appearance.
The Curt C55515 wire connector was the best choice for my lighting needs.

2006 Ford Ranger
Decent looking product. Would have been even better if it worked as advertised. Does not plug into my 2006 Ranger with tow package. Etrailer.com offered to refund the purchase price minus the original shipping cost, plus I had to foot the bill to ship it back. It would have cost more than it's worth. No thanks, I'll just use the pigtail and hard wire it.
Etrailer customer service was very prompt in responding, not that it did me any good.

2014 Jeep Grand Cherokee
Works perfectly! Pulled the cover off the existing plug on my 2014 Grand Cherokee (up under the rear of the vehicle) and this plugged right in.
NOTE: You may have to have the computer flashed by the dealer to enable trailer lighting. This cost me about $45 at a local Dodge dealer.

GMC Terrain
The connector was as described ,no splice and simple. Also i ordered one for my Terrain and a class 2 hitch. Although the harness for the car was the wrong part,the customer service dept. took care of it immediately and it fit and installed with ease. The hitch went on with no problems and their videos showed everything you need to do. These guys will get my business from now on. a+++

2017 Dodge Durango
Installation of the T-Connector was extremely easy once I released the lock that held the factory cover in place, however, I don't recall seeing mention of the fact that the dealer has to "flash the ECU" [computer] to enable and turn on the factory wiring harness. I spent quite a bit of time troubleshooting no lights before finding mention of this on the internet and confirmed with a dealership that wanted $160 to do this work.
by: Dave S06/06/2016
2014 Jeep Grand Cherokee
Trailer hitch fit like a glove and looks great. The wiring harness was exact fit and will have to go to the dealer and have the vehicle part of the wiring turned on. Instruction and video on e-trailer helped a lot to determine my needs and installation.
by: Mitch05/11/2017
2017 Dodge Durango
Installation went well. You will need to cut the spare tire splash cover. Its made of plastic and was easy to cut in place with a, multi tool saw.
Also the Curt T- wiring harness # C55515 plugged in easy as well.
I would also recommend the mounting bracket # 18144 for a nice clean job.
On the 2017 Durango you will have to have the dealer activate the tow plug (flashing the computer ).

Bought this to use on my '03 Trailblazer. Still works good after 1 year of use towing the boat. It even got road tested once since I hadn't plugged it in all the way and it fell out and drug on the ground for a mile or so. :-)
by: Ray11/18/2020
No lights after installation. Don't think it was product's fault. Dealer told me vehicle did not have module for trailer lights, even though it had the connection for your harness. Ugh!
by: Chip H.06/26/2014
After going to many auto stores trying to track down this wiring harness I finally found it at Etrailer. Had the part in my hands before they said it would arrive. Could not beat the price. Thanks again Etrailer.

2014 Jeep Grand Cherokee
Shipped on time. Installed very easily with help from the video tutorial. Works great and easy to connect trailer on and off that is after I went to the dealership so to activate the trailer lights from the computer because I did not have the tow package when I initially bought the car.

Product was easy to install into the Chev Silverado's existing wire harness. The provided zip ties allowed me to route the 4-wire unit beside existing wiring to the hitch receiver area. Be sure to review the provided videos on simple installation.

- Recommended 4-Way Wiring Harnesses for a 2007 Ford Ranger w/ and w/out the Tow Package Installing the Curt T-Connector Vehicle Wiring Harness item # C55515 will not require you to flash the ecu on your 2007 Ford Ranger. This harness installs on the Ford Ranger's with the factory tow package. If your truck didn't come with a 4-way or 7-way connector you will need the Hopkins Plug-In Simple Vehicle Wiring Harness item # HM40655. This harness does not require the ecu to be flashed either.
view full answer... - Troubleshooting the Wiring Harness on a Truck for Trailer Blinker to WorkThe first thing that you will want to do is inspect the 4-Way connector at the rear of your truck. You will want to make sure that it is free of any debris or corrosion. You will then want to test it to make sure the signal is coming through. You can use a Circuit Tester, like part # PTW2993, to see if there is any signal that is coming through. If you have already done both of these steps, then the next thing I recommend doing is inspecting the wiring itself. You will want to look for...
view full answer... - Adding Extra Tail Lights to a 2002 Chevy Silverado with Tommy Lift GateIf your 2002 Chevy Silverado does not have a 7-Way trailer connector at the back then check up around the spare tire for a wiring harness. The harness will either be just blunt cut wires or there will be a round connector. If there is a round connector you can install # C55515 and then use a light kit that plugs into the 4-Way such as # TLL9RK. If the truck already has a 7-Way you can use # 118384 to Tee into the 7-Way wiring and still use # TLL9RK. If there are just blunt cut wires then...
view full answer... - 7 Way Trailer Wiring Recommendation for 2015 Ford ExpeditionIf you trace the 4-way harness back does it end with a round connector like the part # C55515? If so, then what you can do is replace that assembly with the # HM40975 and you'll have a 7 and 4-way. Or you can look to see if you can find that round connector tucked up somewhere behind the bumper area. It SHOULD be there but if not we can still help. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do...
view full answer... - Troubleshooting Trailer Turn Signals Coming on When Brakes are PressedFrom what I can tell from your description it sounds like what you are going to need is a 2-to-3 converter, the Vehicle to Vehicle Tail Light Converter # C56196 in order to make sure when you hit your brakes the turn signals no longer go on. You are going to need Tail Light Isolating Diode System # 38955 as well in order to prevent power feedback. You will just need to ensure you install this system behind the 7-way on your trailer; I have added a link to a video review of this converter...
view full answer... - Recommended 4-Way for a 2004 Chevrolet Silverado Without Tow PackageThe 2004 Chevrolet Silverados should all come with the US Car Connector under the bumper near the spare tire. It is a round plug that will match up to the Curt T-Connector Vehicle Wiring Harness part # C55515. If you are saying you don't have this only option would be a splice-in one, the Curt Upgraded Circuit Protected Powered Tail Light Converter part # C56496.
view full answer... - Troubleshooting Trailer Wiring of 2015 Grand Cherokee That Stopped WorkingIf your factory trailer wiring stopped working it's most likely due to blown fuses or relays under the hood of your 2015 Jeep Grand Cherokee. That's what I would check first. From there if everything looks good it would be time to go to a dealer to see if anything needs to be reflashed. Older Ram trucks used to require their TIPM to be reset if the trailer wiring ever experienced a short.
view full answer... - Trailer Right/Left Blinker Come On Together and Right Side has Constant Power in Trailer ConnectorIt sounds like there is a combination of issues that are causing the problems you are experiencing. Regarding both blinkers going off together when you engage the left blinker, this could be a bad ground. Bad ground connections can cause all sorts of weird problems. Make sure that the truck side and trailer side connectors are properly grounded to clean and corrosion free bare metal surfaces. The truck ground is probably tied into the harness that leads to the connector so no worries if...

- 4-Pole Trailer Wiring Harness for 2006 Ford RangerThe Hopkins Plug-In Simple Vehicle 4-Pole Wiring Harness # HM40655 is intended for vehicles without any factory tow package wiring, although it could still be installed in a truck that does have this feature. This item installs by plugging in to the vehicle at its taillight wiring connectors rather than at the round U.S. Car connector that would be found tucked up under the rear bumper on a tow-package-equipped vehicle. For a vehicle with that round connector (see photo please) you could...

- Recommended Trailer hitch Receiver For a 2008 Ford Ranger 4x4I recommend installing our etrailer Trailer Hitch Receiver # e29AR on your 2008 Ford Ranger 4x4 with the 4.0L 6 cylinder engine. The frame mounted receiver may require the drilling of 2 additional holes as Ford did not drill these holes in every Ford ranger. There is also not a bolt on receiver for your bumper. I have linked the installation instructions below so you can see where the holes are ahead of time to determine if you will need to drill. If you will need a 4-way flat connector...
view full answer... - Troubleshooting Trailer Connectors That Do Not Pass Running Lights or Turn SignalsThe best way to troubleshoot trailer wiring is to first test your Acadia's 4-pole WITHOUT the Curt adapter. This will let you know if the signals are reaching the adapter. Even though the LED test lights may come on, since these take so little power to light up it could be that there is a small residual voltage in the system that is causing them to illuminate even when no actual running light or turn signal is reaching the adapter. You can use a tester like the # PTW2993 to check the Acadia's...

- No Trailer Running Lights on a 2012 Jeep Grand Cherokee If all of the trailer lights are working except the running lights then there could be a few potential causes. For starters, I would check that the trailer running light fuse on your 2012 Jeep Grand Cherokee to make sure it is intact. If this is not the problem then you will want to check the pins inside each trailer connector in addition to the wires leading into the back of them. The wires need to be tight without much play while pulling them and the pins need to be straight and free...
view full answer... - Trailer Hitch Recommendations for a 2014 Jeep Grand Cherokee with Diesel MotorYes, there are trailer hitches available for the diesel models of the 2014 Jeep Grand Cherokee and yes, we can ship them to Canada! If you want a Curt hitch it is # C13182. And there is a Draw-Tite option as well, # 75713, which is rated a little higher than the Curt hitch but of course you are limited to the capacity of the vehicle. I have linked videos showing example installations of both hitches (the one for Draw-Tite is on a Durango but the hitch also fits that vehicle; just an FYI)....
view full answer... - Trailer Hitch Recommendation for a 2014 Jeep Grand Cherokee Altitude with Dual ExhaustAs long as your 2014 Jeep Grand Cherokee is not an SRT-8 or the diesel model, then you have a few different hitches to choose from. The least visible hitches for your Jeep will be either the Hidden Hitch Class III Trailer Hitch, # 87595 (no longer available), or the Draw-Tite Class III Trailer Hitch, # 75699. Hidden Hitch and Draw-Tite are sister companies, so these hitches are identical. They both have a towing capacity of 5,000 lbs and a tongue weight capacity of 500 lbs and they will...
view full answer... - Parts Needed to Tow a Trailer with a 2017 Dodge Durango R/TSince you are wanting to keep your full size spare installed on your 2017 Dodge Durango R/T the trailer hitch that you need to use is the Draw-Tite # 75713. This has a Tongue Weight (TW) rating of 900 lbs and a Gross Trailer Weight (GTW) rating of 6,000 lbs. When used with a weight distribution system the TW stays the same but the GTW jumps up to 7,500 lbs. You will need to consult your owner's manual regarding your max towing capacity as it is typically lower than what the trailer hitch...
view full answer... - Is There a Completely Hidden Hitch Available for the 2020 Dodge Durango?I have a great solution for you to mount a hitch behind the bumper on your 2020 Dodge Durango; have a look at the Draw-Tite Class III Max Frame # DT38MR. This hitch mounts behind the bumper and is accessible via the removable panel on the rear bumper so that it stays hidden when it's not in use. When it comes to wiring, you'll want to use the Tekonsha # 118617 which plugs in behind the driver and passenger side tail lights to provide you with a 4 way connector on the rear of your vehicle....

- Adapting 7-Way Trailer Connector on 2012 Nissan Titan To 4-Pole Connector on TrailerYour Titan would've been factory equipped either with or without the 7-way trailer connector. If there's indeed a connector on the rear, it would be the 7-way. There's a few ways you can go about doing this. The easiest option would be to adapt the 7-way to work with a 4-pole by using a plug-in adapter like part # PK12716. You could also use the # C55515 that you referenced. You'd unplug the wiring harness from the rear of your 7-way, and plug the # C55515 inline with that connection....

Since the lights worked and don't work any longer, I recommend disconnecting the Curt harness from the factory harness, and checking the pins of the factory harness with a circuit tester like # PTW2993. Also check for bent pins as this can be the cause of a poor connection. If the functions work correctly...

There is absolutely no drilling required to install a trailer hitch on your 2017 Dodge Durango, it is a complete bolt-on installation. I recommend the Draw-Tite # 75713 because it will fit even if you have a full-sized spare tire under your vehicle, unlike the option from Curt. For wiring which will give you a 4-way connector and allow you to power your trailer's lights you need Wiring Harness # C56336 if your Durango does NOT have the factory towing package. If...

- What Is Total Length Of Curt T-Connector Vehicle Wiring Harness Item # C55515I confirmed with Curt that the total length of the Curt T-Connector Vehicle Harness, Item # C55515, is 37 inches from end to end.

Even though your 2014 Jeep Grand Cherokee has the factory tow package wiring, the wiring may not be activated. You may have to take the vehicle to the dealership so they can program the computer to activate the Curt T-Connector Vehicle Wiring Harness for Factory Tow Package - 4-Pole Flat Trailer Connector Item # C55515. Should only take about 10 minutes. It is not uncommon on some vehicles that have factory tow package wiring and it not be activated....
view full answer... - Adding a 4-Way Trailer Connector to a 2014 Jeep Grand Cherokee that Did Not Come with Tow PackageAll of the trailer wiring harnesses for the 2014 Jeep Grand Cherokee including # C55515 are designed to fit in place of the factory 7-Way. Since your Jeep did not come with a factory 7-Way you may need to have the dealer reprogram the computer to activate the trailer wiring harness. The harness will plug into the connector though.
view full answer... - Trailer Wiring Replacement Recommendation for a 2007 Ford RangerWas the connector you found on your frame rail a round connector like what the part # C55515 would plug into? If so that would provide you with a 4-way. Or if you are looking of a 7-way you would want the part # 74682. If for some reason you couldn't get a T-connector like the part # HM40655 to work the only other option would be a hardwire kit like part # 18252. The part # HM40655 is a confirmed fit for your truck though and will work as it was designed specifically for your truck.
